Is every rational number a whole number

NO, NOT every rational number is a whole number. A rational number is any number which can be expressed as the quotient of two integers, i.e., a/b, where a and b are both integers and b≠ 0, for example, the whole number 5 is a rational number because 5 = 5/1; 5 and 1 are integers; This is true for any whole number); therefore, ALL whole numbers are rational numbers, but not all rational numbers are whole numbers. The set of whole numbers is the set of all non-negative integers: {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, ... }, but there are an infinite number of rational numbers which are NOT whole numbers, for example, 1/2, 2/3, 5/8, 3/4, 17/5, .6 = 3/5, 2¾ = 11/4, .7 = 7/10, and .1111111 ... = 1/9, -1/2, -1/11, -5/6, -.9, and -14/3.

Hope this helps! :)

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
